The design and construction of the Dublin Port tunnel is a matter for the National Roads Authority, NRA, in co-operation with the relevant local authority. Dublin City Council and the National Roads Authority have developed the Dublin Port tunnel to the highest international standards in terms of safety, both as regards construction and operation. The project was the subject of a lengthy public inquiry during March-April 1999, when the safety aspects were thoroughly examined by the joint inspectors appointed by the Minister for the Environment and Local Government who had responsibility in this regard at the time.
The Dublin Port tunnel has a construction contract value of almost €450 million. The project, while very costly in capital terms, will provide enormous benefits to the city of Dublin and to industry and the economy as a whole when completed in 2005.
